DIAGNOSTICSxfs_metadump returns an exit code of 0 if all readable metadata is successfully copied or 1 if a write erroroccurs or a read error occurs and the -e option used.NOTESAs xfs_metadump copies metadata only, it does not matter if the source filesystem has a realtime section ornot. If the filesystem has an external log, it is not copied. Internal logs are copied and any outstanding logtransactions are not obfuscated if they contain names.xfs_metadump is a shell wrapper around the xfs_db(8) metadump command.
